In Dou Dou’s hand was a palm-sized treasure seal, pitch black as ink, of unknown material. Its surface glowed with a layer of gentle matte, feeling as smooth as warm jade, yet its weight far exceeded that of fine iron, heavy and substantial.

On the seal button, a lifelike mythical creature Bian was carved, its eyes glaring widely, ivory tusks slightly exposed, instilling awe with just a glance.

On the face of the seal were engraved six ancient and robust characters, with bold, vigorous strokes carrying a majestic aura, though their exact meaning was yet to be deciphered.

"Wow, this is great... this is great..." Dou Dou clutched the treasure seal in her hand, tossing it playfully, her little face beaming with excitement, "I found it first, so it’s mine..."

Her delight was interrupted when a shadow approached.

Xiao Yue stood before her, her brow slightly furrowed, extending her pale hand straight before her, speaking calmly, "Hand it over."

Dou Dou’s smile froze instantly, her lips pursed in reluctance, as she begrudgingly placed the treasure seal into Xiao Yue’s palm.

"You look quite unwilling?"

Xiao Yue glanced at the treasure seal in her palm, her fingertips brushing over its icy surface, then looked up at Dou Dou with a teasing gaze.

"No, no..." Dou Dou frantically waved her small hands, shaking her head like a rattle.

"I am not trying to steal from you." Xiao Yue saw through her thoughts and patiently explained, "This is Brother Shen Siyuan’s prize, it should rightfully belong to him."

Dou Dou lowered her head, nodding sulkily.

Xiao Yue spoke no more, turning toward Shen Siyuan and handed the treasure seal over.

Shen Siyuan took it without hesitation.

As his fingertips touched the seal’s surface, a familiar aura spread from his fingers, akin to when he acquired the Qiong State Governor’s Seal.

However, the aura of this treasure seal was heavier, more solemn, exuding the unique dignity and grandeur of the Yin Department.

He gazed down at this treasure seal; the Qiong State Governor’s Seal was carved with the words "Governor Seal, Commanding Ghost Gods," projecting authority and dominance.

The six characters on this treasure seal, ancient and obscure, were difficult to recognize at first glance, but the power hidden within the seal was far more overwhelming than that of the Qiong State Governor’s Seal.

"This seal is extraordinary..." Shen Siyuan thought to himself.

But now was clearly not the best time to study this treasure seal.

The battle tonight had created an uproar; the Incense and Great Sun’s golden light nearly illuminated the entire Yangzhou Netherworld, one could never predict if other powerful existences or forces lurking in the depths of the Netherworld would be drawn in.

Better to leave soon than to linger on.

"Duoduo, take us back." Shen Siyuan spoke decisively, looking at Duoduo nearby.

"What? We’re leaving already?"

Upon hearing this, Dou Dou showed a look of disappointment, her little eyes still glued to the treasure seal in Shen Siyuan’s hand, unwilling to part.

Seeing this, Shen Siyuan couldn’t help but gently tap her little head with a bit of affectionate teasing: "I’ll bring you again next time, but now let’s go home..."

Dou Dou held her tapped little head, stuck out her tongue, and dared not say more.

Duoduo responded immediately, lightly rotating the Qiankun Umbrella in her hand, the patterns of the Pine Wood Immortal Crane on the umbrella surface instantly lit up, enveloping the three in a greenish light curtain.

As the speed of the umbrella handle increased, the surrounding scenery began to warp and overlap, the black soil of the Netherworld, Yin Wind, and the twilight-like glow swiftly dissipated.

At the moment when their figures completely vanished from Yangzhou Netherworld, something suddenly moved beneath the seemingly tranquil black soil in the distance.

A Mud Worm, entirely pitch-black and shaped like a giant earthworm, slowly emerged from the soil.

Its body was thick, covered in viscous black liquid, glinting eerily in the Yin Wind.

Suddenly, this "earthworm’s" body split vertically, revealing densely packed, honeycomb-like holes inside, each one embedded with a blood-red eye, all of them simultaneously shifting, scanning in the direction where Shen Siyuan and his group had disappeared, exuding an eerie horror.

In the next instant, countless tiny mosquitoes buzzed out from the eyes, these mosquitoes were entirely pitch-black, their wings covered in fine scales, resembling a black cloud that quickly vanished into the Netherworld’s darkness, evidently going to convey a message.

And after all the mosquitoes flew out, the gigantic Mud Worm’s body deflated and shrank like a punctured balloon, eventually turning into a wisp of dense Polluted Energy, dissipating into the whistling Yin Wind, as if it had never appeared.

Duoduo’s Qiankun Umbrella was indeed extraordinarily powerful, reversing Qiankun, traversing yin and yang, merely a matter of thought.

Within moments, the greenish light curtain dispersed, and they stood in the living room of their seaside home.

Warm yellow light softy spilled onto the floor, dispelling the chill brought by the Netherworld, moonlight outside had just reached mid-sky, silver beams splashed onto the balcony, blending with indoor lighting, creating a cozy and serene atmosphere.

From the distant seaside, the sound of waves subtly hitting rocks could still be heard, mixed with sporadic laughter from tourists, starkly contrasting the chilling solemnity of the prior Yangzhou Netherworld.

"It’s still early, you three go about your own tasks."

Shen Siyuan turned and sent the three young ones off.

Watching the three little ones leave, Shen Siyuan turned into the study, closing the door behind, isolating the outside commotion.

The study was exceedingly quiet, only the occasional sound of waves crashing from outside the window.

Shen Siyuan sat on the grandmaster chair, placing the pitch-black treasure seal before him on the mahogany desk.

Warm yellow light fell upon the treasure seal, outlining its heavy contours, the Bian seal button under the light appeared increasingly dignified, while the six characters on the face of the seal faintly revealed a hint of golden glow against the backdrop of shadows.

He took a deep breath to steady himself, slowly extended his hand, guiding his Divine Sense from his palm toward the treasure seal on the desk.

But just as his Divine Sense was about to touch the treasure seal, an invisible barrier suddenly emerged, fiercely repelling his Divine Sense, followed by a heart-piercing agony spread from deep within his Divine Sense.

This pain did not come from the physical body but originated from the deepest reaches of the soul, like being pierced by numerous thin steel needles simultaneously, or being forcibly torn apart in the Divine Soul, the excruciating pain made Shen Siyuan’s brow furrow instantly, a layer of fine cold sweat seeping from his forehead.

"This is so powerful?" Shen Siyuan thought, startled.

Shen Siyuan’s Divine Sense, essentially inherited from the residual soul of Jiu You Netherworld Lord.

Jiu You Netherworld Lord had cultivated for thousands of years, a top-tier existence in power, even his residual soul was unmatched by ordinary cultivators; had it not been severely damaged by heavenly tribulations, it wouldn’t have been possible for Shen Siyuan to devour and merge.

Thus, Shen Siyuan’s strongest attribute was his Divine Sense, yet now merely the passive defensive power of a treasure seal caused him unbearable agony, indicating the remarkable origin of this treasure seal.
